る。[0003] In recent years, the bonnet is deformed when the tip of the bonnet is made of resin, or the rigidity of the bonnet frame is reduced. There is a bonnet with a cushioning structure that takes care not to add. However, even if the bonnet has a buffer structure as described above, if a radiator is provided immediately below the bonnet, the radiator suppresses the bending displacement of the bonnet.

な不具合を含むものである。Therefore, when the radiator mounting structure described above is combined with the hood of the buffer structure, a sufficient distance is provided between the bonnet and the radiator, and the bonnet and the radiator are arranged so as to dispose the obstacles. It is necessary to sufficiently alleviate the impact force. However, this requires a large space in the engine room. As a result, a structural design constraint is imposed. For example, the overall length of the vehicle is increased and the weight is increased. In addition, the above-described radiator mounting structure also includes the same disadvantages as described above because the radiator is basically not retracted rearward due to the deformation of the hood or the radiator is not easily collapsed.

なり重量の増大を招くこともない。When a certain amount of force is applied to the radiator to move the radiator rearward, the projection is disengaged from the elastic support portion, and the upper end of the radiator can move rearward around the lower end of the radiator. For example, when an obstacle hits the hood and deforms the hood and the obstacle reaches the radiator, the radiator moves rearward, so that an unnecessary impact is not applied to the obstacle. Therefore, no restrictions are imposed on the structural design, and, for example, the overall length of the vehicle is not increased and the weight is not increased.

FIGS. 5A to 5C are views for explaining the operation of the radiator mounting structure according to the present invention. In (a), the obstacle M hits from the upper front of the vehicle body as shown by the arrow. In (b), the obstacle M crushes the hood 12 and reaches the upper part of the radiator 21 as indicated by an arrow.

能である。In (c), the upper support pin 26 at the upper end of the radiator 21 is connected to the bracket 34 and the support rubber 3.
5 is elastically supported by the upper cross member 32 via the elastic support portion 31 and the lower cross member 42 is swingably mounted on the lower cross member 42 around the lower support pin 27 of the radiator 21 so as to be able to swing behind the vehicle body. When M reaches the upper part of the radiator 21 as shown by the arrow, the upper support pin 26
Is disengaged from the elastic support portion 31, and the radiator 21 swings rearward of the vehicle body around the lower support pin 27 as indicated by an arrow. That is, since the radiator 21 can move rearward, an unnecessary force is not applied to the obstacle. Therefore, the distance between the bonnet 12 and the radiator 21 can be minimized, so that there is no restriction on the structural design, and, for example, the overall length of the vehicle does not increase and the weight does not increase. Since the upper cross member 32 is provided behind the radiator 21 in the vehicle body and is arranged at a position where the trajectory of the radiator 21 is not obstructed, the radiator 21 can swing rearward of the vehicle body without hitting the upper cross member 32.

The same components as those of the upper support structure 22 are denoted by the same reference numerals, and the detailed description is omitted. The upper support structure 52 elastically supports the upper support pin 26 erected on the upper end of the radiator 21, and the elastic support portion 61 from which the upper support pin 26 comes off when the radiator 21 attempts to move backward with a certain force or more. Are provided on the upper cross member 32 side. Elastic support 6
1 is one in which one end of a bracket 64 is attached to the upper cross member 32, and a spring member 65 is attached to the other end of the bracket 64.

い。In the embodiment, as shown in FIG. 3, one upper support pin 26 is erected on the upper end of the radiator 21, and the upper support pin 26 is supported by one elastic support portion 31. However, the present invention is not limited to this example, and a structure in which a plurality of pins are provided at the upper end of the radiator and these are respectively supported by a plurality of elastic support portions may be used.

とができる。According to the present invention, the following effects are exhibited by the above configuration. Claim 1 is that a certain force or more acts on the radiator,
When trying to move backward, the convex part comes off from the elastic support part, and the upper end of the radiator can move backward centering on the lower end of the radiator, for example, an obstacle hits the bonnet and deforms the bonnet. When the obstacle reaches the radiator, the radiator can move backward. Therefore, an unnecessary force is not applied to the obstacle. Further, since the radiator can be moved backward, for example, the distance between the hood and the radiator can be minimized. Accordingly, there is no restriction on the structural design, and a structural design with a high degree of freedom can be achieved.
